make 9o more terminal-like

[DisposaBoy]

9o works quite well as a terminal but old habits are hard to break so make 9o more terminal-like instead.

• impl single-instance mode:
  • instead of creating a new instance for each directory(I use 9o mostly for non-go related stuff so the pkg paradigm doesn't matter so much).
  • it also means that history will always persist and after changing directories
  • it'll always be the desired size, so no need to keep resizing the output panel after changing directories)
  • navigate history with the arrow keys. it's not a normal view anyway, so it shouldn't matter if i break the behaviour
• impl cd and other common commands
• if the entered command isn't found delegate to the user's shell
• add setting to change the color_scheme, just because i can

missing support for relative paths

Does this mean you would support 'go run'?

ex: $ go run xxxx.go

[DisposaBoy]

it aready supports that? what's the issue.. and btw, it's probably better if you use the replay command (documented here https://github.com/DisposaBoy/GoSublime/blob/master/9o.md), go run is, and always will be a second-class citizen to GS
